While the great line from Romeo and Juliet: “a rose by any other name would smell as sweet” rings true, would a digital rose smell as sweet? \u00a0We often think of the digital world as a mere “renaming” of the real world. \u00a0But some interesting effects emerge from digitizing, and one of them is commonly known as aliasing.<\/p>\n
If you\u2019ve danced in a club with strobe lights, you\u2019ve laughed at the slow motion effect that results from your eyes interpolating between positions. Sampling data can be thought of in much the same way.

The piece, Caught<\/a>, involves a man appearing to fly through the air as a strobe light flashes on at just the right moments in a progression of jumps.<\/p>\n
